To understand the essence of this entry, one must first understand the fact that named objects are declared in behavior-define descriptor. Their names are then referred to in bindings all through the page specifications.

However, there are objects used on the page that are anonymous. The first of those kinds are objects reached through path to handler associations. There are also anonymous event listeners. It is the classes associated with these anonymous objects that are declared here.

This is the class definition part of the Struts action class to path association definition.

The reflection of this in the configuration file is discussed in the overview section.
